Was curious, so did some searching. Not familiar with qemu or libvirt,
so might or might not help you.
This seems to have happened in the past, as well. What I can glean
from this bug report is that libvirt and qemu being out of synch caused
it.
https://bugzilla.redhat.com/show_bug.cgi?id=1530346
This bug report in arch seems to support that it is a mismatch.
https://bugs.archlinux.org/task/63516
Both of these are older, so it might be a regression because something
else was fixed. You could try reinstalling qemu on the host. One
comment mentioned restarting libvirt was successful.
A really old link, but it sounds a lot like your problem, so the
solution might still work.
